Notes:2008 Doak Walker Award Winner...Consensus All-American who decided to leave school after his junior season...Greene is five years removed from high school and left Iowa two years ago to attend community college...Returned to rush for 1,850 yards and 20 touchdowns in 2008, eclipsing the 100-yard plateau in all 13 of the team's outings...A thick runner with a large lower body, Greene runs hard and is a load to bring down...Consistently ran through arm tackles at the collegiate level...Runs with a low center of gravity and rarely takes a big hit...Rarely gets knocked backwards...Sees the holes quickly and bursts through with little wasted motion...The fact that he only started one year at Iowa suggests that Greene has plenty of tread left on his tires...Has great quickness and agility for a man his size...Not a true burner, as a lack of high-end speed is his biggest knock...Hasn't been given the opportunity to prove himself as a receiver.
